I dont know if I should add my two pennies worth, but f*ck it !!
I am going off the details in this thread (can't be arsed looking for other figures) if the Fiat Coupe does a 6.4 0-60 sprint, and a
Ibiza Cupra can do it in 7.0 then the 0.6 second gap is going to mean nothing on the road, to be honest, its gonna be hardly noticeable.
Also, as most cars have totally different power deliveries, you can't really say one car will rape another if you have one of them now, and previously had the other in the past. An example would be a LCR and CTR, both have very similar performance on the road, but due to the power deliveries, the LCR appears to be the quicker car.
For one car to be able to 'rape' another, it would have to have a major power/weight advantage (75bhp+), which probably 99% of people on this site would agree with.
